Abstract

Methods and apparatuses for restoring backup data from a database are provided. The method for restoring backup data from a database, the backup data being stored in the database as a plurality of data blocks, comprises receiving specification of a time to which data restoration is desired, comparing the specified time to timestamp information stored for each data block of the backup data in the database, and retrieving a selected data block of the backup data, if the selected data block has an associated timestamp at or earlier than the specified time and no other data blocks of the backup data which correspond to the selected data block have more contemporaneous timestamps between the specified time and the associated timestamp of the selected data block.
